.SH "DESCRIPTION"
.PP
\fBxmlcatalog\fR
is a command line application allowing users to monitor and manipulate
XML
and
SGML
catalogs\&. It is included in
\fBlibxml\fR(3)\&.
.PP
Its functions can be invoked from a single command from the command line, or it can perform multiple functions in interactive mode\&. It can operate on both
XML
and
SGML
files\&.
.SH "OPTIONS"
.PP
\fBxmlcatalog\fR
accepts the following options (in alphabetical order):
.PP
\fB\-\-add \fR\fB\fITYPE\fR\fR\fB \fR\fB\fIORIG\fR\fR\fB \fR\fB\fIREPLACE\fR\fR\fB \fR
.RS 4
Add an entry to
CATALOGFILE\&.
\fITYPE\fR
indicates the type of entry\&. Possible types are:
\fIpublic\fR, \fIsystem\fR, \fIuri\fR, \fIrewriteSystem\fR, \fIrewriteURI\fR, \fIdelegatePublic\fR, \fIdelegateSystem\fR, \fIdelegateURI\fR, \fInextCatalog\fR\&.
\fIORIG\fR
is the original reference to be replaced, and
\fIREPLACE\fR
is the
URI
of the replacement entity to be used\&. The
\fB\-\-add\fR
option will not overwrite
CATALOGFILE, outputting to
stdout, unless
\fB\-\-noout\fR
is used\&. The
\fB\-\-add\fR
will always take three parameters even if some of the
XML
catalog constructs will have only a single argument\&.
.RE
.PP
\fB\-\-add \fR\fB\fIFILENAME\fR\fR
.RS 4
If the
\fB\-\-add\fR
option is used following the
\fB\-\-sgml\fR
option, only a single argument, a
\fIFILENAME\fR, is used\&. This is used to add the name of a catalog file to an
SGML
supercatalog, a file that contains references to other included
SGML
catalog files\&.
.RE
.PP
\fB\-\-convert\fR
.RS 4
Convert SGML catalog to XML\&.
.RE
.PP
\fB\-\-create\fR
.RS 4
Create a new
XML
catalog\&. Outputs to
stdout, ignoring
\fIfilename\fR
unless
\fB\-\-noout\fR
is used, in which case it creates a new catalog file
\fIfilename\fR\&.
.RE
.PP
\fB\-\-del \fR\fB\fIVALUE(S)\fR\fR
.RS 4
Remove entries from
\fICATALOGFILE\fR
matching
\fIVALUE(S)\fR\&. The
\fB\-\-del\fR
option will not overwrite
\fICATALOGFILE\fR, outputting to
stdout, unless
\fB\-\-noout\fR
is used\&.
.RE
.PP
\fB\-\-noout\fR
.RS 4
Save output to the named file rather than outputting to
stdout\&.
.RE
.PP
\fB\-\-no\-super\-update\fR
.RS 4
Do not update the
SGML
super catalog\&.
.RE
.PP
\fB\-\-shell\fR
.RS 4
Run a shell allowing interactive queries on catalog file
\fICATALOGFILE\fR\&. For the set of available commands see
the section called \(lqSHELL COMMANDS\(rq\&.
.RE
.PP
\fB\-\-sgml\fR
.RS 4
Uses
SGML
super catalogs for
\fB\-\-add\fR
and
\fB\-\-del\fR
options\&.
.RE
.PP
\fB\-v\fR, \fB\-\-verbose\fR
.RS 4
Output debugging information\&.
.RE
.PP
Invoking
\fBxmlcatalog\fR
non\-interactively without a designated action (imposed with options like
\fB\-\-add\fR) will result in a lookup of the catalog entry for
\fIENTITIES\fR
in the catalog denoted with
\fICATALOGFILE\fR\&. The corresponding entries will be output to the command line\&. This mode of operation, together with
\fB\-\-shell\fR
mode and non\-modifying (i\&.e\&. without
\fB\-\-noout\fR) direct actions, allows for a special shortcut of the void
\fICATALOGFILE\fR
specification (possibly expressed as "" in the shell environment) appointing the default system catalog\&. That simplifies the handling when its exact location is irrelevant but the respective built\-in still needs to be consulted\&.
.SH "SHELL COMMANDS"
.PP
Invoking
\fBxmlcatalog\fR
with the
\fB\-\-shell \fR\fB\fICATALOGFILE\fR\fR
option opens a command line shell allowing interactive access to the catalog file identified by
\fICATALOGFILE\fR\&. Invoking the shell provides a command line prompt after which the following commands (described in alphabetical order) can be entered\&.
.PP
\fBadd \fR\fB\fITYPE\fR\fR\fB \fR\fB\fIORIG\fR\fR\fB \fR\fB\fIREPLACE\fR\fR\fB \fR
.RS 4
Add an entry to the catalog file\&.
\fITYPE\fR
indicates the type of entry\&. Possible types are:
\fIpublic\fR, \fIsystem\fR, \fIuri\fR, \fIrewriteSystem\fR, \fIrewriteURI\fR, \fIdelegatePublic\fR, \fIdelegateSystem\fR, \fIdelegateURI\fR, \fInextCatalog\fR\&.
\fIORIG\fR
is the original reference to be replaced, and
\fIREPLACE\fR
is the
URI
of the replacement entity to be used\&. The
\fB\-\-add\fR
option will not overwrite
CATALOGFILE, outputting to
stdout, unless
\fB\-\-noout\fR
is used\&. The
\fB\-\-add\fR
will always take three parameters even if some of the
XML
catalog constructs will have only a single argument\&.
.RE
.PP
\fBdebug\fR
.RS 4
Print debugging statements showing the steps
\fBxmlcatalog\fR
is executing\&.
.RE
.PP
\fBdel \fR\fB\fIVALUE(S)\fR\fR
.RS 4
Remove the catalog entry corresponding to
\fIVALUE(S)\fR\&.
.RE
.PP
\fBdump\fR
.RS 4
Print the current catalog\&.
.RE
.PP
\fBexit\fR
.RS 4
Quit the shell\&.
.RE
.PP
\fBpublic \fR\fB\fIPUBLIC\-ID\fR\fR
.RS 4
Execute a Formal Public Identifier lookup of the catalog entry for
\fIPUBLIC\-ID\fR\&. The corresponding entry will be output to the command line\&.
.RE
.PP
\fBquiet\fR
.RS 4
Stop printing debugging statements\&.
.RE
.PP
\fBsystem \fR\fB\fISYSTEM\-ID\fR\fR
.RS 4
Execute a Formal Public Identifier lookup of the catalog entry for
\fISYSTEM\-ID\fR\&. The corresponding entry will be output to the command line\&.
.RE
.SH "ENVIRONMENT"
.PP
\fBXML_CATALOG_FILES\fR
.RS 4
XML
catalog behavior can be changed by redirecting queries to the user\*(Aqs own set of catalogs\&. This can be done by setting the
\fBXML_CATALOG_FILES\fR
environment variable to a space\-separated list of catalogs\&. Use percent\-encoding to escape spaces or other characters\&. An empty variable should deactivate loading the default catalog from
/etc/xml/catalog
or, more specifically,
${sysconfdir}/xml/catalog\&.
